Complex building conditions require specialized solutions that are easily implemented by underslung bridge travelling cranes. The gantry rails are mounted on the ceiling instead of free-standing alone or building columns. Therefore, the best results can be obtained even under a narrow space and difficult conditions.

Huada Heavy Industry underslung bridge travelling cranes has optimized the existing building width by adopting a very small side approach size and a customized main beam cantilever. It is also possible to optimize the highest hook position by placing a main beam between the end carriages.
